BundleBuddy is a free Chrome add-on designed for developers to analyze JavaScript bundles on any webpage. This tool identifies and groups all loaded JavaScript resources, both from the Document Object Model (DOM) and network performance, providing a clear overview of potential duplications. By highlighting these duplicates, it assists developers in pinpointing scripts that may be loaded multiple times, which can lead to performance issues or conflicts.

The add-on features support for grouping by domain and offers a localized interface in English, Spanish, and French. Its intuitive visual cues enable users to easily identify and address redundancy in script loading. Whether for debugging complex sites or simply understanding the JavaScript resources in use, BundleBuddy provides valuable insights for optimizing web performance.
